There's definitely negative ranking effects that I've seen from mismatched hours across citations and the website. Not as important as NAP integrity maybe, but if you intend to have your real hours listed on the website and anywhere else, don't screw around with having fake hours on Google.
If you do intend to have fake hours listed literally everywhere around the local ecosystem, make sure you're a service area business. Bad enough to have your business owner potentially picking up the phone at 2am, it's much worse to annoy a customer with showing up to a closed location.
